Abstract

Textile-based electrodes include a fabric portion having stretch-recovery non-conductive yarns and an electrically conductive region having stretch-recovery electrically conductive yarn filaments. The electrodes can further include float yarns and can be configured in a textured or ribbed construction. When incorporated into a garment, the electrodes can be used to monitor biophysical characteristics, such as the garment wearer'"'"'s heart rate.

Claims

1. A textile-based electrode, comprising:

a first fabric portion comprising (a) stretch-recovery non-conductive yarns and (b) at least one electrically conductive region comprising stretch-recovery electrically conductive yarn filaments, wherein the electrically conductive region comprises a fabric having a textured or ribbed construction, and wherein the electrically conductive region of the first fabric portion comprises a float yarn.

2. The textile-based electrode according to claim 1, wherein the electrically conductive region comprises an elastic yarn at least partially plated with a conductive yarn.

3. The textile-based electrode according to claim 1, wherein the electrically conductive region comprises a portion of hydrophilic material.

4. The textile-based electrode according to claim 1, wherein at least one hydrophobic material is incorporated into the electrically conductive region of the first fabric portion.

5. The textile-based electrode according to claim 1, further comprising a coating of polymer solution on and/or around the electrically conductive region of the first fabric portion.

6. A textile-based electrode, comprising:

a fabric portion having at least one electrically conductive region comprising one or more stretch-recovery electrically conductive yarns, wherein the electrically conductive region further has at least one float yarn.

7. The textile-based electrode of claim 6, wherein the at least one electrically conductive region comprises a fabric having a textured or ribbed construction.

8. The textile-based electrode of claim 6, wherein the electrically conductive region comprises an elastic yarn at least partially plated with a conductive yarn.

9. The textile-based electrode of claim 6, wherein the electrically conductive region comprises a portion of hydrophilic material.

10. The textile-based electrode of claim 6, wherein at least one hydrophobic material is incorporated into the electrically conductive region of the fabric portion.

11. The textile-based electrode of claim 6, further comprising a coating of polymer solution on and/or around the electrically conductive region of the fabric portion.
